Virgin Galactic’s VSS Unity space tourism vehicle has been retired after its seventh flight on Saturday, and it will be at least two years before replacement craft are ready.
Unity took a pilot and four passengers to an altitude of 54.4 miles, just shy of the Kármán line (62 miles) commonly considered to the be the edge of space. It was Unity’s seventh passenger flight in less than a year, and the craft has served its purpose, according to an arstechnica report.
